These are some handy switches
- -D CMAKE_VERBOSE_MAKEFILE=TRUE : get the make-style actual commands instead of just the progress indications.
- -D CMAKE_BUILD_TYPE="RELWITHDEBINFO" : Use some optimization
An example of command-lines for a local build:
- OSG/cmake.txt:
cmake -D CMAKE_BUILD_TYPE:STRING="Release" -D CMAKE_CXX_FLAGS_RELEASE:STRING="-O3 -g -pipe -march=core2 -mfpmath=sse -Wall"\ -D CMAKE_C_FLAGS_RELEASE:STRING="-O3 -g -pipe -march=core2 -mfpmath=sse -Wall" -D CMAKE_INSTALL_PREFIX:PATH="$HOME/FlightGear/fg.git" $1
- SimGear/cmake.txt:
cmake -D CMAKE_BUILD_TYPE:STRING="Release" -D CMAKE_CXX_FLAGS_RELEASE:STRING="-O3 -g -pipe -march=core2 -mfpmath=sse -Wall"\ -D CMAKE_C_FLAGS_RELEASE:STRING="-O3 -g -pipe -march=core2 -mfpmath=sse -Wall" -D CMAKE_INSTALL_PREFIX:PATH="$HOME/FlightGear/fg.git" -D JPEG_FACTORY:BOOL="ON" $1
- FlightGear/cmake.txt:
cmake -D CMAKE_BUILD_TYPE:STRING="Release" -D CMAKE_CXX_FLAGS_RELEASE:STRING="-O3 -g -pipe -march=core2 -mfpmath=sse -Wall"\ -D CMAKE_C_FLAGS_RELEASE:STRING="-O3 -g -pipe -march=core2 -mfpmath=sse -Wall" -D CMAKE_INSTALL_PREFIX:PATH="$HOME/FlightGear/fg.git" $1
Apparently, -D FG_DATA_DIR="/some/path/" will set the default FG_ROOT
