That might be r1932396 ? After r1934847, the CheckCompilerFlag is used but the module is introduced in 3.19. See also https://cmake.org/cmake/help/latest/module/CheckCompilerFlag.html [[[ $ ../cmake-build.sh --cmake=3.14 Configurations: apxs: /usr/bin/apxs2 cmake: /home/jun66j5/cmake/3.14/bin/cmake ctest: /home/jun66j5/cmake/3.14/bin/ctest ctest args: java: /usr/bin/java perl: /usr/bin/perl pod2man: /usr/bin/pod2man py3c: /home/jun66j5/src/subversion/py3c-1.4/include python: /usr/bin/python3 ruby: /usr/bin/ruby swig: /home/jun66j5/swig/3.0.12/bin/swig builddir: /dev/shm/svn-cmake-build.1kNkr/build -- The C compiler identification is GNU 11.4.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- The CXX compiler identification is GNU 11.4.0 -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Found SWIG: /home/jun66j5/swig/3.0.12/bin/swig (found version "3.0.12") CMake Error at CMakeLists.txt:339 (include): include could not find load file: CheckCompilerFlag CMake Error at CMakeLists.txt:343 (check_compiler_flag): Unknown CMake command "check_compiler_flag".

The Intl::Intl is added in 3.20. See https://cmake.org/cmake/help/latest/module/FindIntl.html [[[ -- Found Intl: /usr/include CMake Error at CMakeLists.txt:453 (add_library): add_library cannot create ALIAS target "external-intl" because target "Intl::Intl" is imported but not globally visible. ]]] Currently, the minimum required version 3.14 is not met. At least, it seems that 3.20 is needed. If the minimum required is important, I think we should run the build, test and install in the CI with the minimum version of cmake. -- Jun Omae <[email protected]> (大前 潤)
