We use CMake's FindBZip2 module.

It looks to me like there are two issues:

1. You must specify BZIP2_INCLUDE_DIR=<path to header directory>
2. Setting "BZIP2_LIBRARIES" does not work and you must instead set BZIP2_LIBRARY_RELEASE.

I found that these options works on my system where I've installed libbz2 to $HOME/.mussels/install/host-static:
-D BZIP2_INCLUDE_DIR="$HOME/.mussels/install/host-static/include" \
-D BZIP2_LIBRARY_RELEASE="$HOME/.mussels/install/host-static/lib/libbz2_static.a" \

We will have to update the clamav INSTALL.md file to list this variable name instead of BZIP2_LIBRARIES.

If anyone wants to volunteer to fix it in CMake's sources, CMake is open source and the module is here: https://github.com/Kitware/CMake/blob/master/Modules/FindBZip2.cmake

Subject: [clamav-users] "BZIP2_LIBRARIES" breaks cmake build


Hi,

I am writing to report that the cmake build method will be broken if the
"BZIP2_LIBRARIES" parameter is set.

The build is successful with this :
| cmake .. \
| -D CMAKE_BUILD_TYPE=Release \
| -D ENABLE_JSON_SHARED=OFF \
| -D JSONC_INCLUDE_DIR=<path-to-json-c>/include/json-c \
| -D JSONC_LIBRARY=<path-to-json-c>/lib/libjson-c.a

But it fails when "BZIP2_LIBRARIES" is used :
| cmake .. \
| -D CMAKE_BUILD_TYPE=Release \
| -D ENABLE_JSON_SHARED=OFF \
| -D BZIP2_LIBRARIES=<path-to-bzip2>/lib/libbz2.a \
| -D JSONC_INCLUDE_DIR=<path-to-json-c>/include/json-c \
| -D JSONC_LIBRARY=<path-to-json-c>/lib/libjson-c.a

Between the lines "-- Configuring done" and "-- Generating done", the
following block of text is repeated 17 times :
| CMake Warning (dev) in CMakeLists.txt:
| Policy CMP0111 is not set: An imported target missing its location property
| fails during generation. Run "cmake --help-policy CMP0111" for policy
| details. Use the cmake_policy command to set the policy and suppress this
| warning.
|
| IMPORTED_LOCATION not set for imported target "BZip2::BZip2" configuration
| "Release".
| This warning is for project developers. Use -Wno-dev to suppress it.

If "make" is then invoked, it will stop at 52% of progress :
| [ 51%] Built target tgt_clam_IScab_ext.exe
| [ 51%] Built target tomsfastmath
| libclamav/CMakeFiles/clamav.dir/build.make:2445: *** target pattern contains no '%'. Stop.
| make[1]: *** [CMakeFiles/Makefile2:1562: libclamav/CMakeFiles/clamav.dir/all] Error 2
| make[1]: *** Waiting for unfinished jobs....
| [ 52%] Linking CXX shared library libclamunrar.so
| [ 52%] Built target clamunrar
| make: *** [Makefile:166: all] Error 2

Parameters for other dependencies (e.g. "OPENSSL_CRYPTO_LIBRARY",
"LIBXML2_LIBRARY", etc) have not caused any problem.

This is to confirm that the fix works perfectly.

Many thanks for your help.
It is particularly crucial for those non-standard systems like ours.
