Fixed installation of libqalculatenasc.so (again)

[Mailaender]

The same fix from #47 after it regressed in #56.

See https://build.opensuse.org/package/show/X11:Pantheon/nasc for an integration test.

Hi. I reverted it because it doesn't build with that on launchpad and locally here. I not really know cmake so don't know why.

[Mailaender]

Try to build with cmake -DCMAKE_INSTALL_LIBDIR=/usr/lib then, but I guess Ubuntu has it's own set of macros which take care of that automatically.

[Mailaender]

Alternatively use https://cmake.org/cmake/help/v3.0/module/GNUInstallDirs.html

It builds with that locally. Great. But still there is the problem with launchpad.

For launchpad something like this in debian/rules could fix it:

override_dh_auto_configure:
	dh_auto_configure -- -DCMAKE_INSTALL_LIBDIR=/usr/lib

@phw Thanks a lot. Will try this.

Hello, again right this bug (or almost this). CMAKE_INSTALL_LIBDIR doesn't work.
Right after configuration i can open build/libqalculatenasc/cmake_install.cmake and see this:

$ grep -nRF '${CMAKE_INSTALL_PREFIX}/lib'
libqalculatenasc/cmake_install.cmake:36:  if(EXISTS "$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/lib/libqalculatenasc.so" AND
libqalculatenasc/cmake_install.cmake:37:     NOT IS_SYMLINK "$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/lib/libqalculatenasc.so")
libqalculatenasc/cmake_install.cmake:39:         FILE "$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/lib/libqalculatenasc.so"
libqalculatenasc/cmake_install.cmake:42:  file(INSTALL DESTINATION "${CMAKE_INSTALL_PREFIX}/lib" TYPE SHARED_LIBRARY FILES "/home/nick87720z/dist/nasc/build/libqalculatenasc/libqalculatenasc.so")
libqalculatenasc/cmake_install.cmake:43:  if(EXISTS "$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/lib/libqalculatenasc.so" AND
libqalculatenasc/cmake_install.cmake:44:     NOT IS_SYMLINK "$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/lib/libqalculatenasc.so")
libqalculatenasc/cmake_install.cmake:46:      execute_process(COMMAND "/usr/bin/strip" "$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/lib/libqalculatenasc.so")

Looking to ccmake, LIB_SUFFIX=64 and CMAKE_INSTALL_LIBDIR=lib64.
I can't find, from where it goes.

Yet, mentioned search phrase doesn't appear anywhere in source tree (in any cmake files).

Again update :)
