cmake: set CMAKE_FIND_ROOT_PATH_MODE_PROGRAM=NEVER

2025-11-05T15:57:51Z

According to CMake documentation[1]: [CMAKE_FIND_ROOT_PATH] is a list of directories that contain the target environment. [CMAKE_FIND_ROOT_PATH_MODE_PROGRAM] sets the default behavior for the find_program command. In most cases, find_program is used to search for an executable which will then be executed, e.g. using execute_process or add_custom_command. So in most cases an executable from the build host is required, so setting CMAKE_FIND_ROOT_PATH_MODE_PROGRAM to NEVER is normally preferred. Since CMAKE_FIND_ROOT_PATH is set to the target staging dir, and the toolchain root dir, it will find target programs before the host ones. An example of this problem is if you try to build antiblock from the packages feed after llvm from the video feeds is built. Antiblock will search for clang-format, pickup the target version, and fail to build.

cmake: use RelWithDebInfo, not Debug, with CONFIG_DEBUG

2025-05-10T10:41:26Z

Given the description of the configuration option at its definition in target/sdk/files/Config.in ("Compile packages with debugging info" and "Adds -g3 to the CFLAGS", the more appropriate CMAKE build type is `RelWithDebInfo` rather than `Debug`.

build: fix CMake generator for non-Ninja builds

2024-08-29T17:46:48Z

OpenWRT by default uses the Ninja generator, but some packages disable Ninja and use the default Unix Makefiles generator. This generator can be overridden in the user environment with `CMAKE_GENERATOR`. This patch explicitly sets the correct generator when `PKG_USE_NINJA:=0`. In particular, the `mt76` package uses the Makefiles generator. Signed-off-by: Ivan Romanov Link: https://github.com/openwrt/openwrt/pull/16263 Signed-off-by: Hauke Mehrtens

treewide: make use of new toolchain define

2023-10-20T14:13:56Z

Make use of new toolchain define. TOOLCHAIN_DIR should be used only for toolchain related packages and for everything else TOOLCHAIN_ROOT_DIR and other define should be used instead. Switch to new entry where possible. Signed-off-by: Christian Marangi

build: suppress cmake warnings about unused vars

2023-10-04T10:28:45Z

When cmake is invoked to build a package it usually reports a warning about unused variables passed to it. This is caused by openwrt passing all supported variables to cmake, even if they are not all required by the package being compiled. To reduce clutter when compiling such packages these warnings are now suppressed. Approved-by: Rosen Penev Reviewed-by: Robert Marko Signed-off-by: Tjalling Hattink

treewide: drop use of which

2022-01-17T08:14:26Z

Ubuntu started to flag which as deprecated and it seems which is not really standard and may vary across Distro. Drop the use of which and use the standard 'command -v' for this simple task. Which is still present in the prereq if some package/script still use which. A utility script called command_all.sh is implemented that will just mimic the output of which -a.
