Now we're getting somewhere... Which 2.4 are you on?
To force caching of "-D" variables with older cmake versions, specify a type for each one (the ":STRING" in the modified version below). Also, I would put the -D values before naming the source directory: cmake -G "MSYS Makefiles" -DCMAKE_SYSTEM:STRING=Generic -DCMAKE_C_COMPILER_WORKS:STRING=1 -DCMAKE_CXX_COMPILER_WORKS:STRING=1 -DCMAKE_COMPILER_IS_GNUCC:STRING=1 -DCMAKE_COMPILER_IS_GNUCXX:STRING=1 -DTARGET:STRING=nios2 ../ The reason we are all confused trying to answer your question is that you can do this without the ":STRING" in CMake 2.6. (In fact, I think the caching behavior changed in one of the 2.4.x patch releases because people were mainly confused about why ":STRING=" values were cached but simple "=" values were not.) I think 2.4.8 works the same as 2.6 in this regard.
