Confusing bail-out messages

[Adriaan de Groot]

As usual, I fired up CMake without setting up my build environment properly, 
and got this:

CMake Error: Error in cmake code at
/usr/local/KDE4/share/apps/cmake/modules/FindQt4.cmake:1048:
MESSAGE Qt qmake not found!
Current CMake 
stack: /home/adridg/KDE/kdepim/CMakeLists.txt;/usr/local/share/CMake/Modules/CMakeCInformation.cmake;/usr/local/share/CMake/Modules/CMakeCXXInformation.cmake;/usr/local/share/CMake/Modules/FindKDE4.cmake;/usr/local/KDE4/share/apps/cmake/modules/FindKDE4Internal.cmake;/usr/local/KDE4/share/apps/cmake/modules/FindQt4.cmake


For once, though, I actually read the messages, and it strikes me that they 
are somewhat confusing when taken at face value. For one thing, there is no 
error in the cmake code: it's a error during configuration because the cmake 
code has *detected* an error. It might be useful to make the bail-out message 
a little more verbose with some MESSAGE( STATUS ... ) strings (I'll try to 
remember to do that on monday to avoid the wrath of everyone).

The other thing is the stack: it'd be useful to include line numbers in the 
trace and/or format it like the gcc "error in file F, included from F' ..." 
error listing.
