I have just now tried the "NMake Makefiles JOM" generator for my
build_projects project, and I ran into a peculiar issue.
For example (from the "jom VERBOSE=1 build_ndiff" output) and with
single lines split up for e-mail purposes
Z:\home\wine\newstart\cmake-2.8.10.2-win32-x86\bin\cmake.exe -E
make_directory
Z:/home/wine/newstart/build_script/build_dir-git_jom/build_projects/Source/build_ndiff
works fine, but the next command,
Z:\home\wine\newstart\cmake-2.8.10.2-win32-x86\bin\cmake.exe -E copy
z:/home/software/plplot_svn/HEAD/plplot_allura/cmake/build_projects/ndiff/CMakeLists.txt
Z:/home/wine/newstart/build_script/build_dir-git_jom/build_projects/Source/build_ndiff/CMakeLists.txt
silently fails to copy the file and the build continues happily a bit
further until it errors out when that missing file is required.
Never mind. It appears that jom is unreliable for some reason when run
from bash. This silent error disappears if I run it from cmd instead.
Anybody understand why?
cmd is really a pretty lame command-line environment when you are used to the
power of
bash. But I held my nose and continued...
Which brings us to the next peculiar "NMake Makefiles JOM" generator
issue. I could only capture the last part of the output
from running the cmake command, but here is what that said for the
ndiff build
Z:\home\wine\newstart\build_script\build_dir-git_jom>Z:\home\wine\newstart\jom-1.0.13\jom.exe
build_shapelib-configure
[.... lost]
-- The C compiler identification is unknown
-- Check for working C compiler: cl
CMake Warning at CMakeLists.txt:2 (PROJECT):
To use the JOM generator, cmake must be run from a shell that can use the
compiler cl from the command line. This environment does not contain
INCLUDE, LIB, or LIBPATH, and these must be set for the cl compiler to
work.

The MinGW suite of compilers is on the PATH. Why doesn't cmake -G
"NMake Makefiles JOM" find those automatically?
I will attempt to follow the advice to set CMAKE_C_COMPILER to gcc
out of curiosity to see if I can eventually make this work, but my
initial impressions of "NMake Makefiles JOM" are not good due to this
CMake issue with the default compiler choice for this generator
and also jom's silent unreliability when it is run from bash rather
than the cmd shell.
