# @BLURB: common ebuild functions for cmake-based packages |
16 |
# @DESCRIPTION: |
17 |
# The cmake-utils eclass is base.eclass(5) wrapper that makes creating ebuilds for |
18 |
# cmake-based packages much easier. |
19 |
# It provides all inherited features (DOCS, HTML_DOCS, PATCHES) along with out-of-source |
20 |
# builds (default), in-source builds and an implementation of the well-known use_enable |
21 |
# and use_with functions for CMake. |
22 |
|
23 |
# @ECLASS-VARIABLE: WANT_CMAKE |
24 |
# @DESCRIPTION: |
25 |
# Specify if cmake-utils eclass should depend on cmake optionaly or not. |
26 |
# This is usefull when only part of aplication is using cmake build system. |
27 |
# Valid values are: always [default], optional (where the value is the useflag |
28 |
# used for optionality) |
