 qgis3 fails build on Mojave.  The failure is in the configuration step,
 and is caused by a failure to find the header file `gl.h`.

 The workaround is simple (and was mentioned in a comment on commit f2ee940
 by i0ntempest.  On Mojave (and perhaps earlier version of macOS), the
 patch
 {{{
 - configure.sdkroot
 ${developer_dir}/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
 + configure.sdkroot       ${developer_dir}/Developer/SDKs/MacOSX.sdk
   cmake.install_prefix    ${applications_dir}
 }}}
 needs to be reverted.

 I did this manually and qgis3 built to completion.

 Veence, are you building on Catalina?  The configure.sdkroot line probably
 needs to be conditioned on the OS version.
