- Previously we used message priority: SEND_ERROR when a package was not found and find_package() was called without QUIET or REQUIRED, which emits an error message, and prevents generation, but continues configuration. - The fact SEND_ERROR induces an error message was confusing for users as it implies that something bad has happened and they cannot continue, when in fact we were disabling the option in question and were thus able to continue, all they had to do was re-configure. - This commit also reorders the search lists for includes/libraries so that we always search user installed locations (e.g. /usr/local) before system installed locations. Thus we will now always prefer a user install to a system install if both are available, which is likely to be the users desired intention. Change-Id: Ide84919f27d3373f31282f70c685720cd77a6723

# FindCXSparse.cmake - Find CXSparse libraries & dependencies.
|
|
#
|
|
# This module defines the following variables which should be referenced
|
|
# by the caller to use the library.
|
|
#
|
|
# CXSPARSE_FOUND: TRUE iff CXSparse and all dependencies have been found.
|
|
# CXSPARSE_INCLUDE_DIRS: Include directories for CXSparse.
|
|
# CXSPARSE_LIBRARIES: Libraries for CXSparse and all dependencies.
|
|
#
|
|
# CXSPARSE_VERSION: Extracted from cs.h.
|
|
# CXSPARSE_MAIN_VERSION: Equal to 3 if CXSPARSE_VERSION = 3.1.2
|
|
# CXSPARSE_SUB_VERSION: Equal to 1 if CXSPARSE_VERSION = 3.1.2
|
|
# CXSPARSE_SUBSUB_VERSION: Equal to 2 if CXSPARSE_VERSION = 3.1.2
|
|
#
|
|
# The following variables control the behaviour of this module:
|
|
#
|
|
# CXSPARSE_INCLUDE_DIR_HINTS: List of additional directories in which to
|
|
# search for CXSparse includes,
|
|
# e.g: /timbuktu/include.
|
|
# CXSPARSE_LIBRARY_DIR_HINTS: List of additional directories in which to
|
|
# search for CXSparse libraries, e.g: /timbuktu/lib.
|
|
#
|
|
# The following variables are also defined by this module, but in line with
|
|
# CMake recommended FindPackage() module style should NOT be referenced directly
|
|
# by callers (use the plural variables detailed above instead). These variables
|
|
# do however affect the behaviour of the module via FIND_[PATH/LIBRARY]() which
|
|
# are NOT re-called (i.e. search for library is not repeated) if these variables
|
|
# are set with valid values _in the CMake cache_. This means that if these
|
|
# variables are set directly in the cache, either by the user in the CMake GUI,
|
|
# or by the user passing -DVAR=VALUE directives to CMake when called (which
|
|
# explicitly defines a cache variable), then they will be used verbatim,
|
|
# bypassing the HINTS variables and other hard-coded search locations.
|
|
#
|
|
# CXSPARSE_INCLUDE_DIR: Include directory for CXSparse, not including the
|
|
# include directory of any dependencies.
|
|
# CXSPARSE_LIBRARY: CXSparse library, not including the libraries of any
|
|
# dependencies.
|
|
|
|
# Called if we failed to find CXSparse or any of it's required dependencies,
|
|
# unsets all public (designed to be used externally) variables and reports
|
|
# error message at priority depending upon [REQUIRED/QUIET/<NONE>] argument.
