Thanks for the info.
To find the options with cmake, run:
cmake -LH
Normally you are inside the source, where CMakeLists.txt is.
With mariadb:
$ cd mariadb-
$ cmake . -LH
I wrote that, because the case of x264 is a little peculiar: the source
with CMakeLists.txt is not under x264_1.8, but under "source", so that:
$ cd x264_1.8
$ cmake source -LH
Unfortunately there is no ENABLE_STATIC option, so we have to do either
what you have just done, or use a patch to create the option. I have
submitted that patch and modified the x264 page to use it should be in
svn tomorrow.
Attached is the patch, if you wish to try it before that.
Use
cmake -DCMAKE_INSTALL_PREFIX=/usr \
-DENABLE_STATIC=OFF ../source
