Subject: [PATCH] opengl: missing library check
|
|
|
|
Traditionally the presence of the header file was not considered
|
|
sufficient, though this was somewhat forgotten with the prevalence of
|
|
pkg-config.
|
|
|
|
However most libraries have portable headers, while the shared library
|
|
is platform-dependent. It is common for the header to be present while
|
|
the library is absent with "multilib" installations (i.e. Linux
|
|
installation with multiple architectures).
