[CMake] cmake 2.6.4 won't find boost 1.40 on windows

[Cristian Adam]

Hi,

I have encountered problems with Boost 1.40 (build on Windows using
Visual Studio 2008 and MinGW GCC 4.4.0) with CMake 2.6.4.

Boost was compiled for Visual Studio 2008 like this:
bjam --build-dir=c:\temp\boost toolset=msvc --build-type=complete install
and for MinGW GCC like this:
bjam --build-dir=c:\temp\boost toolset=gcc --build-type=complete install

Adding set(Boost_ADDITIONAL_VERSIONS "1.40" "1.40.0") didn't fix the
problem.

The problem is due to the fact that Boost 1.40 was installed to
c:\boost\include\boost-1_40\ and according to FindBoost.cmake module 
lines 292 to 300:

    FOREACH(_boost_VER ${_boost_TEST_VERSIONS})
      # Add in a path suffix, based on the required version, ideally
      # we could read this from version.hpp, but for that to work we'd
      # need to know the include dir already
      if (WIN32 AND NOT CYGWIN)
        set(_boost_PATH_SUFFIX boost_${_boost_VER})
      else (WIN32 AND NOT CYGWIN)
        set(_boost_PATH_SUFFIX boost-${_boost_VER})
      endif (WIN32 AND NOT CYGWIN)

Boost should have been installed into c:\boost\include\boost_1_40\.

Was Boost before version 1.40 installed into "boost_1_3x" for Visual 
Studio and MinGW?
If so how should version 1.40 be detected for Visual Studio and MinGW?

I have tested two solutions to this problem:

1. rename c:\boost\include\boost-1_40\ to c:\boost\include\boost_1_40\
2. use set(BOOST_INCLUDEDIR "c:/boost/include/boost-1_40"

The following cmake change:
http://www.cmake.org/pipermail/cmake-commits/2009-August/006975.html
will remove the "set(Boost_ADDITIONAL_VERSIONS "1.40" "1.40.0")" 
statement but it won't fix the
underscore problem for Visual Studio and MinGW Boost compilations!

Cheers,
Cristian.
