This fixes some cases where transitive libraries, as nominated by a component library, were not being absorbed into a metalib, due to the library actually not being defined yet. This makes the logic a little more robust, first by explicitly requiring a metalib definition to come after all component library definitions, and second to assume a library "linked" to a component library is a non-component if it isn't defined (yet).
Building with CMake
The quickest way to build and install panda with CMake is to run:
cmake .
make
[sudo] make install
Instead, it is recommended to create a separate directory to build Panda3D:
mkdir build
cd build/
cmake ..
make
To configure CMake, it is recommended to use cmake-gui (cmake-gui .),
however it is also possible to configure it entirely through CMake's
command-line interface; see man cmake for more details.
In general, the config variable for a particular third party library is:
HAVE_<LIBRARY>=True/False # Example: USE_JPEG
Panda subpackage building is handled by:
BUILD_<SUBPACKAGE>=True/False # Example: BUILD_DTOOL, BUILD_PANDA
Other configuration settings use their historical names (same names as in-source):
# Examples
PANDA_DISTRIBUTOR="MyDistributor"
LINMATH_ALIGN=On
# ... etc ...
For example, makepanda.py --distributor X becomes cmake -DPANDA_DISTRIBUTOR=X
All found third-party libraries are enabled by default. Most config settings are set to a sensible default for typical a PC/desktop Panda3D distribution. Third-party libraries and other settings can be enabled or disabled through configuration with the cmake gui or cli.
Running Panda3D with -DCMAKE_BUILD_TYPE= and one of Release, Debug,
MinSizeRel, or RelWithDebInfo will cause some configuration settings
to change their defaults to more appropriate values.
If cmake has already been generated, changing the build type will not cause some of these values to change to their expected values, because the values are cached so that they don't overwrite custom settings.
To reset CMake's config to defaults, delete the CMakeCache.txt file, and rerun
CMake with the preferred build mode specified
(example: cmake .. -DCMAKE_BUILD_TYPE=Debug).
