Just FYI:
I wrote own (simplier) FindBoost but more specific to my needs. The main
feature is this approach relies on standard linux installations (single
version installed into directory without numbers), but works on our windows
configurations too.
I used following approach to get boost version:
find_path(BOOST_INCLUDE_DIR boost/version.hpp)
if(BOOST_INCLUDE_DIR)
file(WRITE "${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/check_boost.cxx"
"#include <boost/version.hpp>\n#include <iostream>\nint
main(){std::cout <<
BOOST_LIB_VERSION << std::endl; return 0; }\n")
try_run(BOOST_TEST_RUNS BOOST_TEST_COMPILES
${CMAKE_BINARY_DIR}
"${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/check_boost.cxx"
CMAKE_FLAGS "-DINCLUDE_DIRECTORIES:STRING=${BOOST_INCLUDE_DIR}"
OUTPUT_VARIABLE BOOST_VERSION
)
if(BOOST_TEST_COMPILES)
string(REGEX MATCH "1_3[34]_?[0-9]*" BOOST_VERSION
${BOOST_VERSION})
message(STATUS "Found Boost version ${BOOST_VERSION}")
else(BOOST_TEST_COMPILES)
set(BOOST_VERSION "")
endif(BOOST_TEST_COMPILES)
endif(BOOST_INCLUDE_DIR)
It may be slower, but provides better encapsulation.
