CMAKE_FIND_PACKAGE_SORT_ORDERΒΆ
The default order for sorting packages found using find_package()
.
It can assume one of the following values:
NONE
Default. No attempt is done to sort packages. The first valid package found will be selected.
NAME
Sort packages lexicographically before selecting one.
NATURAL
Sort packages using natural order (see
strverscmp(3)
manual), i.e. such that contiguous digits are compared as whole numbers.
Natural sorting can be employed to return the highest version when multiple
versions of the same library are found by find_package()
. For
example suppose that the following libraries have been found:
libX-1.1.0
libX-1.2.9
libX-1.2.10
By setting NATURAL
order we can select the one with the highest
version number libX-1.2.10
.
set(CMAKE_FIND_PACKAGE_SORT_ORDER NATURAL)
find_package(libX CONFIG)
The sort direction can be controlled using the
CMAKE_FIND_PACKAGE_SORT_DIRECTION
variable
(by default decrescent, e.g. lib-B will be tested before lib-A).
