[CMake] Using CMake as a VC7 workspace generator with external makefiles

[Richard Maunder]

Hi Brad,

Thanks for the reply. Yes I think ADD_CUSTOM_TARGET could work for
making the makefile call.

However I am stuck with another problem - which I didn't explain well. I
have a top-level CMakelists.txt:

PROJECT (MyProj)
SUBDIRS(Mod1 Mod2 Mod3 .....)
ADD_CUSTOM_TARGET(....call to make......)

Then in each Mod1, Mod2 etc subdir a CMakelist.txt:

FILE(GLOB Hdrs inc/*.h)
FILE(GLOB Srcs src/*.cxx src/*.c)
ADD_LIBRARY(gl ${Hdrs} ${Srcs})

I'd like CMake to generate a VC7 Makefile Project - equivalent to
setting the 'Configuration Type' in the General Properties of an
exisiting VC7 Proj to 'Makefile' - for each of these modules/subdirs.
I'd like the GLOB'd sources to be hung off this, and ideally be able to
specify the various parameters for this project type (make exe path /
args etc).

I thought prehaps there might be a CMAKE_XXX var or some other way to do
this? ADD_LIBRARY / ADD_EXECUTABLE only seem to be capable of making
lib/dll/exe projects?

Thanks

Richard
