On buildbots, the building directory seems to be not a subdir of
a git repo, so a variable expands into an empty string which in turn
results in a syntax error:
--snip--
-- Looking for in6addr_any - found
-- Found Git: /data/bowl-builder/arm_cortex-a5/build/sdk/staging_dir/host/bin/git (found version "2.1.4")
fatal: Not a git repository (or any parent up to mount point /data)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
CMake Error at CMakeLists.txt:114 (if):
if given arguments:
"STREQUAL" "/data/bowl-builder/arm_cortex-a5/build/sdk/build_dir/target-arm_cortex-a5_musl_eabi/libiio-0.11"
Unknown arguments specified
-- Configuring incomplete, errors occurred!
--snap--
The patch quotes the if arguments and thus fixes the build.
