[cmake-developers] cmake selftest use different compiler and binutils as configured on Darwin

[Claus Klein]

I tried to check if ninja works now on Darwin, but some tests still  
fails.

I use this configuration, but I have the gcc-4.7 installed too under / 
opt/local/bin.

/usr/local/bin/cmake -G "Ninja" -DCMAKE_TEST_GENERATOR:STRING="Ninja" \
    -DCMAKE_TEST_MAKEPROGRAM:FILEPATH="${MAKECOMMAND}" - 
DCMAKE_ENABLE_NINJA:BOOL="ON" \
    -DCMAKE_C_COMPILER="/opt/local/libexec/ccache/gcc-4.2" - 
DCMAKE_CXX_COMPILER="/opt/local/libexec/ccache/g++-4.2" \
    -DCMAKE_LINKER:FILEPATH=/usr/bin/ld \
    -DCMAKE_AR:FILEPATH=/usr/bin/ar \
    -DCMAKE_RANLIB:FILEPATH=/usr/bin/ranlib \
    -DMAKECOMMAND:STRING="${MAKECOMMAND} -d stats" \
    -DBUILD_CursesDialog:BOOL="ON" -DBUILD_QtDialog:BOOL="OFF" \
    ../cmake


The build works fine, but some test still fails!
see http://open.cdash.org/viewTest.php?onlyfailed&buildid=2421596

As you can see at build command, the configured binutils are not used  
while test?


Than I tried this:

clausklein/Downloads/CmakeNinjaBuildDir/bin/ctest "--build-and-test" "/

libexec/ccache/gcc-4.2" -DCMAKE_CXX_COMPILER="/opt/local/libexec/

DCMAKE_AR:FILEPATH=/usr/bin/ar -DCMAKE_RANLIB:FILEPATH=/usr/bin/ranlib

What goes wrong with this test?
