Subject: [PATCH] Allow building shared or static library only
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patchs retrieved from:
 - https://git.buildroot.net/buildroot/tree/package/zmqpp/0001-Allow-building-shared-or-static-library-only.patch
 - https://git.buildroot.net/buildroot/tree/package/zmqpp/0002-Install-static-library-for-static-builds.patch

Both patches have been merged in a single one and slightly updated to
keep default behavior of building and installing static library
(BUILD_STATIC is set to yes by default)
