Build failure with boost 1.70.0 & cmake 3.14.4

[wich]

Trying to build innoextract with boost 1.70.0 & cmake 3.14.4 results in the error message No suitable boost_iostreams variant has been identified!

Tried version 1.7 as well as current master (38ae68f), both fail with the same error.

cmake command:

cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_DATADIR=share -DCMAKE_INSTALL_DOCDIR=share/doc -DCMAKE_INSTALL_INCLUDEDIR=include -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_INSTALL_MANDIR=share/man -DCMAKE_PREFIX_PATH=share/apps/cmake/modules -DCMAKE_INSTALL_SYSCONFDIR=/etc -DCMAKE_C_FLAGS_RELEASE="-march=core2 -fPIC -DPIC -pipe -O3" -DCMAKE_CXX_FLAGS_RELEASE="-march=core2 -fPIC -DPIC -pipe -O3" -DBoost_DEBUG=ON ..

Additional notes; adding -DBUILD_SHARED_LIBS=ON -DBoost_USE_STATIC_LIBS=OFF to the cmake call allows the checks to pass, but then the linking phase fails with many undefined reference to various boost symbols, e.g.:

Try -DBoost_NO_BOOST_CMAKE=ON.

@orbea thanks that works.
@dscharrer I guess the cmake files still need updates for boost 1.70.0 compatibility

Just tried with cmake version 3.13.5, no change, same errors.

Finding Boost is handled by CMake and this needs to be fixed there.
