Makefile variables:
DESTDIR
Destination directory for the install targets, useful to prepare packages
- or install Libav in cross-environments.
+ or install FFmpeg in cross-environments.
Makefile targets:
all
Default target, builds all the libraries and the executables.
+fate
+ Run the fate test suite, note you must have installed it
+
+fate-list

+

libswscale/swscale-test
Build the swscale self-test (useful also as example).
+
+Useful standard make commands:
+make -t <target>
+ Touch all files that otherwise would be build, this is useful to reduce
+ unneeded rebuilding when changing headers, but note you must force rebuilds
+ of files that actually need it by hand then.
+
+make -j<num>
+ rebuild with multiple jobs at the same time. Faster on multi processor systems
+
+make -k
+ continue build in case of errors, this is useful for the regression tests
+ sometimes but note it will still not run all reg tests.
