Subject: This file provides the function ecm_generate_pri_file().

ECM_GENERATE_PRI_FILE() creates a .pri file for a library so that qmake-based
apps can more easily use the library.
It also sets ECM_MKSPECS_INSTALL_DIR as the directory to install the .pri file to.

+# This file provides the function ecm_generate_pri_file().
+# ECM_GENERATE_PRI_FILE() creates a .pri file for a library so that qmake-based
+# apps can more easily use the library.
+# It also sets ECM_MKSPECS_INSTALL_DIR as the directory to install the .pri file to.
+#
+# Requirement: ${PROJECT_VERSION_STRING} must be set before ecm_generate_pri_file.
+# This is usually done by calling ecm_setup_version, which sets it.
+#
+# Syntax:
+#   ecm_generate_pri_file(BASE_NAME baseName
+#                         LIB_NAME libName
+#                         [DEPS "dep1 dep2"]
+#                         [FILENAME_VAR filename_variable] )
+#
+# * baseName is the name which .pro files will use to refer to the library, i.e. the public name, like KArchive.
+# * libName is the name of the actual library to link to, i.e. the first argument to add_library().
+# * the deps are a space-separated list of base names of other libraries. Use core, widgets, etc. for Qt libs.
+# * filename_variable is the name of a variable, which will be set to contain the path of the .pri file to install
+#
+# Example usage:
+#   ecm_generate_pri_file(BASE_NAME KArchive LIB_NAME KF5KArchive DEPS "core" FILENAME_VAR PRI_FILENAME)
+#   install(FILES ${PRI_FILENAME} DESTINATION ${ECM_MKSPECS_INSTALL_DIR})

+# This default value makes "installing qt and this lib into the same prefix" work out of the box.
+# Packagers who use -DCMAKE_INSTALL_PREFIX=/usr will certainly want to set ECM_MKSPECS_INSTALL_DIR to something like share/qt5/mkspecs/modules
