I am trying to write a script that will build multiple cppUtes lib.a files for different sanitizers with a bash script.

When trying to pass the compiler flags as variables to cmake I am unable to correctly format them. Please see the brief example below.

```bsh
#!/bin/sh
set -euo pipefail
COMMON_OPTS='-fno-common -g -fno-omit-frame-pointer'
ASAN_OPT='-fsanitize=address'
ASAN_C_FLAGS="-DCMAKE_C_FLAGS=\"$ASAN_OPT $COMMON_OPTS\""

echo "cmake ../ $ASAN_C_FLAGS"
cmake ../ $ASAN_C_FLAGS
make

```

The output of echo is what I expect, and what works for setting flags when not running in a bash script: 

```
cmake ../ -DCMAKE_C_FLAGS="-fsanitize=address -fno-common -g -fno-omit-frame-pointer"

```

However, when I run the script cmake is not interpreting the flags correctly. They do not appear in the cmake flags that are displayed during the configuration:

```
CppUTest CFLAGS: -include "/home/ubuntu/cpputest/include/CppUTest/MemoryLeakDetectorMallocMacros.h" -Wall -Wextra -pedantic -Wshadow -Wswitch-default -Wswitch-enum -Wconversion -Wsign-conversion -Wno-padded -Wno-long-long -Wstrict-prototypes

```

and finally, I get the following compilation error from make:

```
c++: error: unrecognized argument to '-fsanitize=' option: 'address -g -fno-omit-frame-pointer'

```

Any help would be kindly appreciated.
