#
# This module manages build mode environment, including variables, compiler
# flags and CMake policies.
#
# The main difference between this module and ManageEnvironmentCommon are:
# - ManageEnvironmentCommon is called by both script and build mode;
# while this module is called by only build mode.
# - ManageEnvironmentCommon should be invoked before project definition;
# this module should be invoked after project definition.
# - ManageEnvironmentCommon caches only variables;
# this module not only caches variables, but also set the compiler flags.
#
# Included Modules:
# - ManageMessage
#
# Reads following variables:
# - CMAKE_INSTALL_PREFIX: Install directory used by install.
# - PROJECT_NAME: Project name.
#
# Set cache for following variables:
# - PRJ_DATA_DIR: Project data dir
# Default: ${DATA_DIR}/${PROJECT_NAME}
# - PRJ_DOC_DIR: Project doc dir
# Default: ${DOC_DIR}/${PROJECT_NAME}
#
# Defines following compile flags: (which use variables with same names)
# - CMAKE_INSTALL_PREFIX
# - PROJECT_NAME
# - BIN_DIR
# - DATA_DIR
# - DOC_DIR
# - SYSCONF_DIR
# - LIB_DIR
# - LIBEXEC_DIR
# - PRJ_DATA_DIR
# - PRJ_DOC_DIR
#
# Note: compile flag PRJ_VER is defined in ManageVersion.
#
# Defines following functions:
# SET_COMPILE_ENV(<var> [<defaultValue>] [ENV_NAME <envName>]
# [CACHE <type> <docstring> [FORCE]]
# )
# - Ensure a variable is set to nonempty value, then set the value
# to the compile flags with same name.
#
# The value is determined by first non-empty value:
# 1. Value of <var>.
# 2. Value of environment variable <var>,
# or if ENV_NAME is specified, value of <envName>.
# 3. <defaultValue>
# * Parameters:
# + var: Variable to be set
# + defaultValue: Default value of the var
# + envName: (Optional)The name of environment variable.
# Only need if different from var.
# + CACHE type docstring [FORCE]:
# Same with "SET" command.
