[CMake] ExternalProject BUILD_COMMAND and Visual Studio Express 2010

[David Cole]

I use the environment variable:

     VS110COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 
11.0\Common7\Tools\

to locate Visual Studio 2012 (vs11) on my machine.

So, in CMake code, you could use $ENV{VS110COMNTOOLS} to specify the 
path to the batch file if you need it.

The easiest thing to do is probably a find_program(nmake).... and if 
it's not found put up a warning message, saying "you need to run this 
build from a Visual Studio command prompt".


HTH,
David

I don't know of any sure way of doing that, but if vcvarsall.bat is
located in the same relative place across all versions of VS then it
might be possible to sort of misuse some variable that CMake sets.

I had a quick look in one project I build with VS2010 and found one
candidate variable: CMAKE_LINKER.

   CMAKE_LINKER           = C:/Program Files (x86)/Microsoft Visual 
Studio
10.0/VC/bin/link.exe
   vcvarsall.bat location = C:/Program Files (x86)/Microsoft Visual 
Studio
10.0/VC/vcvarsall.bat

I'd consider that a terrible hack though, so hopefully there's someone
else with a better idea.
