There were several issues caused by travis-ci using cmake-3.2.2 instead of what I have locally, cmake-3.7.2: - FIND_PACKAGE(PkgConfig) sets PKG_CONFIG_FOUND, not PkgConfig_FOUND. - Set cache internal variables instead of parent scope. (Probably not needed, but it's a good idea.) - Older PkgConfig CMake modules don't support PKG_GET_VARIABLE(), so use defaults for Nautilus and Thunar extension directories in that case. - Added diagnostic messages for older PkgConfig. - Print the cmake version in travis-ci. Squashed commit of the bugfix/travis-ci-gtk branch.

# Find a library using PkgConfig.
|
|
#
|
|
# Required variables:
|
|
# - _prefix: Variable prefix.
|
|
# - _prefix: pkgconfig package name. (Used for variable prefixes.)
|
|
# - _include: Include file to test.
|
|
# - _library: Library name, without the leading "lib".
|
|
# - _target: Name for the imported target.
|
|
#
|
|
# If found, the following variables will be defined:
|
|
# - ${_prefix}_FOUND: System has the package.
|
|
# - ${_prefix}_INCLUDE_DIRS: Package include directories.
|
|
# - ${_prefix}_LIBRARIES: Package libraries.
|
|
# - ${_prefix}_DEFINITIONS: Compiler switches required for using the package.
|
|
# - ${_prefix}_VERSION: Package version.
|
|
#
|
|
# In addition, if a package has extensiondir or extensionsdir set,
|
|
# the appropriate ${_prefix}_* variable will also be set.
|
|
#
|
|
# A target with the name ${_target} will be created with all of
|
|
# these definitions.
