Instead of checking whether the library path ends up somewhere in /usr, set the architecture prefix, anyway. The library path mechanism is also used in custom prefixes, without this change, the library gets installed globally on Debian and Ubuntu, leading to non-standard behaviour and cross-build problems, as multiple architecture builds of this library can't be installed alongside each other. This is the minimal change to correct this behaviour from upstream cmake.

# GNUInstallDirs
|
|
# --------------
|
|
#
|
|
# Define GNU standard installation directories
|
|
#
|
|
# Provides install directory variables as defined for GNU software:
|
|
#
|
|
# ::
|
|
#
|
|
# http://www.gnu.org/prep/standards/html_node/Directory-Variables.html
|
|
#
|
|
# Inclusion of this module defines the following variables:
|
|
#
|
|
# ::
|
|
#
|
|
# CMAKE_INSTALL_<dir> - destination for files of a given type
|
|
# CMAKE_INSTALL_FULL_<dir> - corresponding absolute path
|
|
#
|
|
# where <dir> is one of:
|
|
#
|
|
# ::
|
|
#
|
|
# BINDIR - user executables (bin)
|
|
# SBINDIR - system admin executables (sbin)
|
|
# LIBEXECDIR - program executables (libexec)
|
|
# SYSCONFDIR - read-only single-machine data (etc)
|
|
# SHAREDSTATEDIR - modifiable architecture-independent data (com)
|
|
# LOCALSTATEDIR - modifiable single-machine data (var)
|
|
# LIBDIR - object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian)
|
|
# INCLUDEDIR - C header files (include)
|
|
# OLDINCLUDEDIR - C header files for non-gcc (/usr/include)
|
|
# DATAROOTDIR - read-only architecture-independent data root (share)
|
|
# DATADIR - read-only architecture-independent data (DATAROOTDIR)
|
|
# INFODIR - info documentation (DATAROOTDIR/info)
|
|
# LOCALEDIR - locale-dependent data (DATAROOTDIR/locale)
|
|
# MANDIR - man documentation (DATAROOTDIR/man)
|
|
# DOCDIR - documentation root (DATAROOTDIR/doc/PROJECT_NAME)
|
|
#
|
|
# Each CMAKE_INSTALL_<dir> value may be passed to the DESTINATION
|
|
# options of install() commands for the corresponding file type. If the
|
|
# includer does not define a value the above-shown default will be used
|
|
# and the value will appear in the cache for editing by the user. Each
|
|
# CMAKE_INSTALL_FULL_<dir> value contains an absolute path constructed
|
|
# from the corresponding destination by prepending (if necessary) the
|
|
# value of CMAKE_INSTALL_PREFIX.
