I need to put the kernel headers in a non standard location, and I want to do it automatically with yum, so I downloaded the rpm corresponding to the current headers in the latest version of CentOS, and made the following SPEC file:

%global PKG_NAME linux-headers
%global SRC_NAME kernel-headers

%global RISE_DISTRIBUTED_PATH /opt/distributed_tools

%global SRC_PATH %_sourcedir
%global BUILD_PATH %_builddir
%global INSTALL_PATH %_buildrootdir%DISTRIBUTED_PATH

%global PKG_VER %(uname -r | sed 's/-/./g')

Name: distributed_kernel_headers
Version: %PKG_VER
Release: 1%?dist
Summary: The Linux kernel Headers


License: GPLv2
Group: System Environment/Kernel

URL: http://www.kernel.org/

Source: kernel.rpm

BuildRequires: yum-utils, sed, rpmdev-tools
Provides: distributed_headers

%description
Kernel-headers includes the C header files that specify the interface
between the Linux kernel and userspace libraries and programs. The
header files define structures and constants that are needed for
building most standard programs and are also needed for rebuilding the
glibc package.


%prep
cd %BUILD_PATH
mkdir %PKG_NAME

%build
cd %BUILD_PATH/%PKG_NAME
rpm2cpio %SRC_PATH/%(SRC_NAME)* | cpio -idvm --owner=$(whoami) &> /dev/null

%install
##rm -rf %buildroot
mkdir -pv %INSTALL_PATH/%PKG_NAME"-$(uname -r)"
mkdir -pv %INSTALL_PATH/include/%PKG_NAME/
cp -R %BUILD_PATH/%PKG_NAME/usr/include/* %INSTALL_PATH/%PKG_NAME"-$(uname -r)"
# ln -s %INSTALL_PATH/%PKG_NAME"-$(uname -r)"/* %INSTALL_PATH/include/%PKG_NAME/

%files
%defattr(-,root,root,-)
/opt/

%clean
rm -Rf %BUILD_PATH %_buildrootdir

Everything works fine with rpmbuild -ba until the file section, in which the following error appears:

 error: File not found by glob: /home/make_toolchain/rpmbuild/BUILDROOT/distributed_kernel_headers-3.10.0.693.21.1.el7.x86_64-1.el7.centos.x86_64/opt

According to everything that I've read, the file section looks for the files in %_buildrootdir, but in this case this is not happening, and I do not know what is causing this error.

Also there is no special variable set for the rpmbuild enviroment. And every file gets writen to %_builrootdir/opt/distributed_tools/
