03 / ORIGINAL ISSUE TEXT
yhirose/cpp-httplib #638 · read the original issue
the quote marks in the cmake file confuse cmake and result in the command line doing silly things like `-D\"CPPHTTPLIB_BROTLI_SUPPORT\"`. Which confuses everything involved resulting in a failed build.
solution is to change the following:
```cmake
# Set the definitions to enable optional features
target_compile_definitions(${PROJECT_NAME} ${_INTERFACE_OR_PUBLIC}
$<$<BOOL:${HTTPLIB_IS_USING_BROTLI}>:"CPPHTTPLIB_BROTLI_SUPPORT">
$<$<BOOL:${HTTPLIB_IS_USING_ZLIB}>:"CPPHTTPLIB_ZLIB_SUPPORT">
$<$<BOOL:${HTTPLIB_IS_USING_OPENSSL}>:"CPPHTTPLIB_OPENSSL_SUPPORT">
)
```
to
```cmake
# Set the definitions to enable optional features
target_compile_definitions(${PROJECT_NAME} ${_INTERFACE_OR_PUBLIC}
$<$<BOOL:${HTTPLIB_IS_USING_BROTLI}>:CPPHTTPLIB_BROTLI_SUPPORT>
$<$<BOOL:${HTTPLIB_IS_USING_ZLIB}>:CPPHTTPLIB_ZLIB_SUPPORT>
$<$<BOOL:${HTTPLIB_IS_USING_OPENSSL}>:CPPHTTPLIB_OPENSSL_SUPPORT>
)
```
