Comment (by florian@…):

 I would be happy to oblige but using the cmake portgroup is not as
 straightforward as it seems. When I set
 {{{
 PortGroup                   cmake 1.0
 configure.cflags-append     -DNDEBUG -fstrict-aliasing
 }}}
 in Portfile, cmake is invoked with
 {{{
 -DCMAKE_C_FLAGS="-I/opt/local/include" -DCMAKE_C_FLAGS_RELEASE="-Os"
 }}}
 When I reorder:
 {{{
 configure.cflags-append     -DNDEBUG -fstrict-aliasing
 PortGroup                   cmake 1.0
 }}}
 cmake is invoked with:
 {{{
 -DCMAKE_C_FLAGS="-I/opt/local/include" -DCMAKE_C_FLAGS_RELEASE="-Os
 -DNDEBUG -fstrict-aliasing"
 }}}
 CMake's `CMAKE_C_FLAGS_RELEASE` defaults to `-O3 -NDEBUG` but you never
 get this when leaving `configure.cflags` blank.

 Btw, where does the `-Os` come from. I never set `configure.optflags`.

 To get CMake's default `DCMAKE_C_FLAGS_RELEASE` I would have to specify
 this (in order):
 {{{
 configure.optflags          -O3
 configure.cflags-append     -DNDEBUG
 PortGroup                   cmake 1.0
 }}}

 I haven't yet seen another portfile including cmake portgroup after
 setting configure options. I'm puzzled.
