I need to use mangrove (mongo ODM lib over mongo-c-driver and mongo-cxx-driver) and included this into my project as CMake ExternalProject_Add command, with a dependency on mongo-c-driver/mongo-cxx-driver
mongocxx generates CMake configuration scripts with a names like :
libmongocxx-config.cmake
libmongocxx-config-version.cmake
and no issues to find these by mangrove with that script:
set(LIBMONGOCXX_REQUIRED_VERSION 3.1.3)
set(LIBMONGOCXX_REQUIRED_ABI_VERSION v_noabi)
find_package(libmongocxx ${LIBMONGOCXX_REQUIRED_VERSION} REQUIRED)
However mongo-c-driver generates those scripts with a name which incudes ABI version into file names.
libmongoc-1.0-config.cmake
libmongoc-1.0-config-version.cmake
and similar CMake code:
set(LIBMONGOC_REQUIRED_VERSION 1.7.0)
set(LIBMONGOC_REQUIRED_ABI_VERSION 1.0)
find_package(LibMongoC ${LIBMONGOC_REQUIRED_VERSION} REQUIRED)
can't find out the scripts.
Of course, if I manually remove the version from file names, it can find those files, but I'd like to fix the problem in a script and on mangove side.
So the question about CMake techniques :
Is there an ability to specify the version of package which will automatically used by (inside CMake scripts names) find_package command to look for?
According to find_package documentation, the version is embedded inside the libmongocxx-config-version.cmake file.
This means that if you want to get the package libmongoc-1.0-config.cmake, you should use:
find_package(libmongoc-1.0 ${LIBMONGOC_REQUIRED_VERSION} REQUIRED)
