Subject: [Buildroot] [PATCH v2 3/5] package/hidapi: convert to cmake-package
Date: Fri, 13 Nov 2026 15:51:59 +0100	[thread overview]
Message-ID: <20261113145201.2357363-4-tomas.mudrunka@gmail.com> (raw)
In-Reply-To: <20261113145201.2357363-1-tomas.mudrunka@gmail.com>

Upstream considers the autotools build system deprecated and going to
be obsolete, and recommends using CMake instead (see BUILD.autotools.md
and BUILD.md). The CMake build system also allows to select which
backends are built (see the HIDAPI_WITH_* options), and avoids the
need to autoreconf the package.

Both backends (hidraw and libusb) are still built, so the installed
shared libraries (with the same libhidapi-*.so.0 SONAME), headers and
pkg-config files are unchanged; the .pc files are generated from the
same pc/*.pc.in templates.

The LIBS="-liconv" workaround is no longer needed: the libusb backend
uses find_package(Iconv) and links against libiconv when the C library
does not provide iconv.

As usual with cmake-package, only shared libraries are built when
BR2_SHARED_STATIC_LIBS=y, while the autotools build also installed the
static ones. No in-tree package links statically against hidapi in
that configuration.

The hidtest program and unit tests default to ON only for Debug
builds; disable them explicitly so they are never built.
