Hi Peter,
as I don't use windows at all, this is just a very wild guess...
Could it be that in the second run you actually don't use
/CMake/share/cmake-3.2/Modules/FindBoost.cmake
but boost-config.cmake, which it now finds in the cached environment of
the first run?
This assumes of course that you built boost w/ CMake and not bjam...
Cheers,
Benedikt

Hi to all,
I tested this with cmake 3.2.2 and 3.3.2 and still get the same problem.
I'd like to use boost with gcc on windows 7 64bit. I installed boost and gcc
with msys2 as I cannot use MSVC for the actual project I am looking into for
this.
the funny thing, if I use the attached CMakeLists.txt on the machine and call:
```
$ cmake -G "MSYS Makefiles" -DBOOST_ROOT=C:/msys64/mingw64 -
DBOOST_LIBRARYDIR==C:/msys64/mingw64/lib ..
-- The CXX compiler identification is GNU 4.9.2

Boost.

I'd like to link statically to multithreaded libboost_*-mt.a from my app. But
it proofes really hard to find Boost in the first place.
Any ideas?
Peter
