Bug ID: 1674
Summary: CMakeLists: Improper override of CMAKE_C_FLAGS
Product: PCRE
Version: 10.20 (PCRE2)
Hardware: x86-64
OS: Windows
Status: NEW
Severity: bug
Priority: medium
Component: Code
Assignee: p...@hermes.cam.ac.uk
Reporter: roy.ivy....@gmail.com
CC: pcre-dev@exim.org
CMakeLists.txt includes:
```
SET(CMAKE_C_FLAGS -I${PROJECT_SOURCE_DIR}/src)
```
which overrides any custom CMAKE_C_FLAGS.
It should include any prior setting by instead using:
```
SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -I${PROJECT_SOURCE_DIR}/src")
```
This is necessary for customization such as increasing the stack size during
compilation (using `cmake -D CMAKE_C_FLAGS=-Wl,--stack,8000000 ...`).
Thanks for investigating.
