# CMake configuration for pkgconf
#
# Caution: this assumes you don't set CMAKE_BUILD_TYPE
#
# FIXME: this isn't a native cmake approach, it's just a straight translation
# of configure.ac + Makefile.am, barely good enough to work on Linux, Mac, and Windows.

# Require recent cmake, but not so recent that Ubuntu 16.04 users have to upgrade.
