Yes

and PROJ_BUILD_VERSION should not be set to current:revision:age, but to X.Y.Z 
which only non-mortals can guess from current:revision:age. The pragramatic 
way of having X.Y.Z right is to do a autoconf build and look at the generated 
libproj.so.X.Y.Z . But this would only work on the operating system from which 
you did the build, since the libtool current:revision:age versionning scheme 
translates to different X.Y.Z versions given the operating system... So it 
seems there's no way to make sure that a cmake build will result in the same 
.so.* files as a autoconf+libtool build
