Comment (by RJVB):

 Replying to [ticket:66874 RJVB]:
 > Or simply install the version created by the cmake build because that
 lacks the entire offending section (which appears dispensable anyway).

 The following expression in the post-destroot will have the same effect,
 removing the line that says "don't have CMAKE_SIZEOF_VOID_P" and
 everything below:

 {{{
 reinplace "/ have CMAKE_SIZEOF_VOID_P/,\$d"
 ${destroot}${prefix}/lib/cmake/expat-${version}/expat-config-version.cmake
 }}}

 Alternatively, create a manual version of the file that ends with

 {{{
 # if the installed or the using project don't have CMAKE_SIZEOF_VOID_P
 set, ignore it:
 if("${CMAKE_SIZEOF_VOID_P}" STREQUAL "")
   return()
 endif()

 # check that the installed version has the same 32/64bit-ness as the one
 which is currently searching:
 if(CMAKE_SIZEOF_VOID_P STREQUAL "4" OR CMAKE_SIZEOF_VOID_P STREQUAL "8")
   math(EXPR installedBits "${CMAKE_SIZEOF_VOID_P} * 8")
   set(PACKAGE_VERSION "${PACKAGE_VERSION} (${installedBits}bit)")
   set(PACKAGE_VERSION_UNSUITABLE TRUE)
 endif()
 }}}
