[CMake] FindBoost: find both win32 and x64 static libs

[Hicham Mouline]

I was wrong. Dmytro pointed out that bjam allows building boost libraries
with the compiler and bitness in the boost library name --layout=versioned.

Therefore, I could have both 32 and 64bit versions in the same directory.

I wonder then if FindBoost is able to detect automatically the right ones
based on the name of the libs.

 

regards

As boost libraries naming convention doesn't include in the lib names
whether they are built by msvc9 win32 or x64, I am forced on a winxp 64 box
where I hold both versions to have a different lib directory under
boost_root.

I set BOOST_ROOT then call FIND_PACKAGE(Boost 1.44 COMPONENTS ...).

Am I supposed to detect which of vc9 32bit or 64bit am  I generating for and
then set BOOST_LIBRARYDIR depending on that before calling FIND_PACKAGE?

How do I detect bitness?

 

You could try something like this:

 

include(CheckTypeSize)

CHECK_TYPE_SIZE(void* SIZEOF_PTR)

message("size of pointer = ${SIZEOF_PTR}")

 

Then if SIZEOF_PTR is 4, you would set BOOST_LIBRARYDIR to be
${BOOST_ROOT}/lib32 and if it is 8, you set it to ${BOOST_ROOT}/lib64.
