I don't know why。please help me

[cloudecker]

You need to specify the pkg- config path.(run cmake with the additional parameter -DPKG_CONFIG_EXECUTABLE="your pkg-config path").

@allenwen1 anything better with @cloudecker suggestion ?

[shattars3d]

@allenwen1 you using el captain, el captain has issues with cmake, Apple removed some header files... try to downgrade your osx.. to yosemite which works../

[akallabeth]

Apple is shipping some libraries in a new format (tbd).
They can not be found by older versions of cmake, but recent releases should cover support for those.
Can you check your version of cmake in use with cmake --version?
From what I have found versions > 3.3.1 should work.

[akallabeth]

Closing due to lack of feedback. Feel free to reopen if the issue still persists.

How did you solve the problem? Can you please share?
Thanks!
