Summary: export(PACKAGE) prioritizes build-tree over
install-tree
Description:
The package BoostAny depends on BoostCore. Both packages create a Config file in
the build tree and install one in the install tree. There is a export(PACKAGE)
call for each of them.
If I set CMAKE_PREFIX_PATH to the install location of BoostAny, I can use
find_package(BoostAny) and it will find it in the install location.
However, as BoostAnyConfig.cmake has a find_package(BoostCore) inside it, the
BoostCore package is found in the build-tree instead of the install tree. As the
BoostAny and BoostCore packages are both installed and beside each other in the
filesystem, this is an unintuitive result.
The find_package documentation does not state the order of prefixes searched for
packages. It seems to me that the export(PACKAGE) prefixes should be a fallback
after trying in the CMAKE_PREFIX_PATH, but I don't know if that can be changed
now.
It would be possible to use find_package( ... PATHS ${CMAKE_CURRENT_LIST_DIR} )
in BoostAnyConfig.cmake, but that would require that all Boost packages be
installed to the same prefix. It may be that they want to be able to install
different libraries to different prefixes (I don't know, but I think CMake
should allow it).
