# - Manage build environment such as environment variables and compile flags.
2
# This module predefine various environment variables, cmake policies, and
5
# The setting can be viewed and modified by ccmake.
7
# List of frequently used variable and compile flags:
8
# + CMAKE_INSTALL_PREFIX: Compile flag whose value is ${CMAKE_INSTALL_PREFIX}.
9
# + BIN_DIR: Directory for executable.
10
# Default: ${CMAKE_INSTALL_PREFIX}/bin
11
# + DATA_DIR: Directory for architecture independent data files.
12
# Default: ${CMAKE_INSTALL_PREFIX}/share
13
# + DOC_DIR: Directory for documentation
14
# Default: ${DATA_DIR}/doc
15
# + SYSCONF_DIR: System wide configuration files.
17
# + LIB_DIR: System wide library path.
18
# Default: ${CMAKE_INSTALL_PREFIX}/lib for 32 bit,
19
# ${CMAKE_INSTALL_PREFIX}/lib64 for 64 bit.
20
# + LIBEXEC_DIR: Executables that are not meant to be executed by user directly.
21
# Default: ${CMAKE_INSTALL_PREFIX}/libexec
22
# + PROJECT_NAME: Project name
24
# Defines following macros:
25
# SET_COMPILE_ENV(var default_value [ENV_NAME env_name]
26
# [DISPLAY type docstring])
27
# - Add compiler environment with a variable and its value.
28
# If the variable is not defined in cmake, the value is obtained from
30
# 1. Environment variable with the same name (or specified via ENV_NAME)
31
# 2. Parameter default_value
33
# + var: Variable to be set
34
# + default_value: Default value of the var
35
# + env_name: (Optional)The name of environment variable.
36
# Only need if different from var.
37
# + type: is used by the CMake GUI to choose a widget with
38
# which the user sets a value. Valid values are:
39
# PATH = Directory chooser dialog.
40
# STRING = Arbitrary string.
41
# BOOL = Boolean ON/OFF checkbox.
42
# INTERNAL = No GUI entry (used for persistent variables).
43
# + docstring: Label to show ing CMAKE GUI.
45
# SET_USUAL_COMPILE_ENVS()
46
# - Set the most often used variable and compile flags.
47
# It defines compile flags according to the values of corresponding variables,
48
# usually under the same or similar name.
49
# If a corresponding variable is not defined yet, then a default value is assigned
50
# to that variable, then define the flag.
52
# Defines following flags according to the variable with same name.
53
# + CMAKE_INSTALL_PREFIX: Compile flag whose value is ${CMAKE_INSTALL_PREFIX}.
54
# + BIN_DIR: Directory for executable.
55
# Default: ${CMAKE_INSTALL_PREFIX}/bin
56
# + DATA_DIR: Directory for architecture independent data files.
57
# Default: ${CMAKE_INSTALL_PREFIX}/share
58
# + DOC_DIR: Directory for documentation
59
# Default: ${DATA_DIR}/doc
60
# + SYSCONF_DIR: System wide configuration files.
62
# + LIB_DIR: System wide library path.
63
# Default: ${CMAKE_INSTALL_PREFIX}/lib for 32 bit,
64
# ${CMAKE_INSTALL_PREFIX}/lib64 for 64 bit.
65
# + LIBEXEC_DIR: Executables that are not meant to be executed by user directly.
66
# Default: ${CMAKE_INSTALL_PREFIX}/libexec
67
# + PROJECT_NAME: Project name
68
# + PRJ_VER: Project version
69
# + PRJ_DATA_DIR: Data directory for the project.
70
# Default: ${DATA_DIR}/${PROJECT_NAME}
71
# + PRJ_DOC_DIR: DocuFILEPATH = File chooser dialog.
72
# Default: ${DOC_DIR}/${PROJECT_NAME}-${PRJ_VER}
