Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

CMake: Fix ncurses linking issue on FreeBSD The linker is unable to find libncurses.so.6.2 on FreeBSD. If I change Curses::curses from an UNKNOWN library to an INTERFACE library, then it works fine. While UNKNOWN appears to be preferred by the CMake community, it seems like it doesn't add -L/usr/local/lib to the LDFLAGS on my FreeBSD test machine where /usr/local isn't used by default. Disclaimer: This fix feels like a bit of a hack, but it works for me.

CMake: Fix find-curses issue with static libs If ncurses or pdcurses are static libraries, they are not properly detected. First, the user compiling clamav needs to specify if the include path is for NCURSES or PDCURSES, which will differentiate the two. I've updated the INSTALL.md file to show this. Second, the wrong variable was being used to add the include path to the Curses::curses target, which means that clamdtop would fail to include ncurses.h. I fixed this.

Changed the default to build milter on non-macOS, non-Windows operating systems. - Fix LD_LIBRARY_PATH for tests including on macOS where LD_LIBRARY_PATH and DYLD_LIBRARY_PATH must be manually propagated to subprocesses. - Use UNKNOWN IMPORTED library instead of INTERFACE IMPORTED library for pdcurses, but still use INTERFACE IMPORTED for ncurses. UNKNOWN IMPORTED appears to be required so that we can use $<TARGET_FILE_DIR:Curses::curses> to collected the pdcurses library at install time on Windows. - When building with vcpkg on Windows, CMake will automatically install your app local dependencies (aka the DLL runtime dependencies). Meanwhile, file(GET_RUNTIME_DEPENDENCIES ...) doesn't appear to work correctly with vcpkg packages. The solution is to use a custom target that has CMake perform a local install to the unit_tests directory when using vcpkg. This is in fact far easier than using GET_RUNTIME_DEPENDENCIES in the unit_tests for assembling the test environment but we can't use this method for the non-vcpkg install because it won't collect checkDynamic.dll for us because we don't install our tests. We also can't link with the static check.lib because the static check.lib has pthreads symbols linked in and will conflict with our pthread.dll. TL;DR: We'll continue to use file(GET_RUNTIME_DEPENDENCIES ...) for assembling the test enviornment on non-vcpkg builds, and use the local install method for vcpkg builds. testcase.py: Wrapped a Pathlib.unlink() call in exception handling as the missing_ok optional parameter requires a Python version too new for common use. Remove localtime_r from win32 compat lib. localtime_r may be present in libcheck when building with vcpkg and while making it a static function would also solve the issue, using localtime_s instead like we do everywhere else should work just fine. check_clamd: Limited the max # of connections for the stress test on Mac to 850, to address issues found testing on macos-latest on GitHub Actions.

add_library(Curses::curses UNKNOWN IMPORTED)
Add CMake build tooling This patch adds experimental-quality CMake build tooling. The libmspack build required a modification to use "" instead of <> for header #includes. This will hopefully be included in the libmspack upstream project when adding CMake build tooling to libmspack. Removed use of libltdl when using CMake. Flex & Bison are now required to build. If -DMAINTAINER_MODE, then GPERF is also required, though it currently doesn't actually do anything. TODO! I found that the autotools build system was generating the lexer output but not actually compiling it, instead using previously generated (and manually renamed) lexer c source. As a consequence, changes to the .l and .y files weren't making it into the build. To resolve this, I removed generated flex/bison files and fixed the tooling to use the freshly generated files. Flex and bison are now required build tools. On Windows, this adds a dependency on the winflexbison package, which can be obtained using Chocolatey or may be manually installed. CMake tooling only has partial support for building with external LLVM library, and no support for the internal LLVM (to be removed in the future). I.e. The CMake build currently only supports the bytecode interpreter. Many files used include paths relative to the top source directory or relative to the current project, rather than relative to each build target. Modern CMake support requires including internal dependency headers the same way you would external dependency headers (albeit with "" instead of <>). This meant correcting all header includes to be relative to the build targets and not relative to the workspace. For example, ... ```c include "../libclamav/clamav.h" include "clamd/clamd_others.h" ``` ... becomes: ```c // libclamav include "clamav.h" // clamd include "clamd_others.h" ``` Fixes header name conflicts by renaming a few of the files. Converted the "shared" code into a static library, which depends on libclamav. The ironically named "shared" static library provides features common to the ClamAV apps which are not required in libclamav itself and are not intended for use by downstream projects. This change was required for correct modern CMake practices but was also required to use the automake "subdir-objects" option. This eliminates warnings when running autoreconf which, in the next version of autoconf & automake are likely to break the build. libclamav used to build in multiple stages where an earlier stage is a static library containing utils required by the "shared" code. Linking clamdscan and clamdtop with this libclamav utils static lib allowed these two apps to function without libclamav. While this is nice in theory, the practical gains are minimal and it complicates the build system. As such, the autotools and CMake tooling was simplified for improved maintainability and this feature was thrown out. clamdtop and clamdscan now require libclamav to function. Removed the nopthreads version of the autotools libclamav_internal_utils static library and added pthread linking to a couple apps that may have issues building on some platforms without it, with the intention of removing needless complexity from the source. Kept the regular version of libclamav_internal_utils.la though it is no longer used anywhere but in libclamav. Added an experimental doxygen build option which attempts to build clamav.h and libfreshclam doxygen html docs. The CMake build tooling also may build the example program(s), which isn't a feature in the Autotools build system. Changed C standard to C90+ due to inline linking issues with socket.h when linking libfreshclam.so on Linux. Generate common.rc for win32. Fix tabs/spaces in shared Makefile.am, and remove vestigial ifndef from misc.c. Add CMake files to the automake dist, so users can try the new CMake tooling w/out having to build from a git clone. clamonacc changes: - Renamed FANOTIFY macro to HAVE_SYS_FANOTIFY_H to better match other similar macros. - Added a new clamav-clamonacc.service systemd unit file, based on the work of ChadDevOps & Aaron Brighton. - Added missing clamonacc man page. Updates to clamdscan man page, add missing options. Remove vestigial CL_NOLIBCLAMAV definitions (all apps now use libclamav). Rename Windows mspack.dll to libmspack.dll so all ClamAV-built libraries have the lib-prefix with Visual Studio as with CMake.

INTERFACE_COMPILE_OPTIONS "${PC_PDCurses_CFLAGS_OTHER}"
CMake: Fix find-curses issue with static libs If ncurses or pdcurses are static libraries, they are not properly detected. First, the user compiling clamav needs to specify if the include path is for NCURSES or PDCURSES, which will differentiate the two. I've updated the INSTALL.md file to show this. Second, the wrong variable was being used to add the include path to the Curses::curses target, which means that clamdtop would fail to include ncurses.h. I fixed this.
