Since the same source tree is to be used to generate Win32 and z/OS, I
think I want to tell it "This is a z/OS run" using a flag. I thus
created zcmake.bat:

Visual Studio no matter what. And since Visual Studio *is* correct when
building Win32, I don't want to change the CMakeLists.txt.

You should be using out of source builds.


mkdir win32
cd win32
cmake -DCMAKE_TOOLCHAIN_FILE:string="../myproject/win32.cmake" -G"Unix 
Makefiles"
make

cd ..
mkdir zOS
cd zOS
cmake -DCMAKE_TOOLCHAIN_FILE:string="../myproject/zos.cmake" -G"Unix 
Makefiles"
make
