2017-08-02Add unistd.h checks back to the CMake build.costan1-0/+6
getpagesize(), as well as its POSIX.2001 replacement sysconf(_SC_PAGESIZE), is defined in <unistd.h>. On Linux and OS X, including <sys/mman.h> is sufficient to get a definition for getpagesize(). However, this is not true for the Android NDK. This CL brings back the HAVE_UNISTD_H definition and its associated header check. This also adds a HAVE_FUNC_SYSCONF definition, which checks for the presence of sysconf(). The definition can be used later to replace getpagesize() with sysconf().
2017-07-28Redo CMake configuration.costan2-9/+1
The style was changed to match the official manual [1], the install configuration was simplified and now matches the official packaging guide [2], and the config files use the CMake-specific variable syntax ${VAR} instead of the autoconf-compatible syntax @VAR@, as documented in [3]. The public header files are declared as such (for CMake 3.3+), and the generated headers are included in the library target definition. The tests are only built if SNAPPY_BUILD_TESTS (default ON) is true, so zippy can be easily used in projects that add_subdirectory() its source code directly, instead of using find_package().

2017-07-25Clean up CMake header and type checks.costan1-58/+24
Unused macros: HAVE_DLFCN_H, HAVE_INTTYPES_H, HAVE_MEMORY_H, HAVE_STDLIB_H, HAVE_STRINGS_H, HAVE_STRING_H, HAVE_SYS_BYTESWAP_H, HAVE_SYS_STAT_H, HAVE_SYS_TYPES_H, HAVE_UNISTD_H. Used but never set macros: HAVE_LIBLZF, HAVE_LIBQUICKLZ. These only gate conditional includes. The code that takes advantage of them was removed. Unused types: ssize_t. The testing code uses HAVE_FUNC_MMAP, which was not wired in the CMake build, causing a whole test to be skipped.
