Procedures to reproduce this issue are as follows. 
 1. Unzipping caf_flash.zip to C:
cs\v2.5.2
rf\samples folder. 
 2. cd C:
cs\v2.5.2
rf\samples\caf_flash 
 3. west build -b nrf5340dk_nrf5340_cpuapp 
 
 The following are log messages of west build. 
 C:
cs\v2.5.2
rf\samples\caf_flash>west build -b nrf5340dk_nrf5340_cpuapp

I have fixed this issue by changing CMakeLists.txt as follows. 
 cmake_minimum_required(VERSION 3.20.0)

set(PM_STATIC_YML_FILE ${CMAKE_CURRENT_SOURCE_DIR}/configuration/${BOARD}/pm_static.yml)
message(STATUS "PM_STATIC_YML_FILE: ${PM_STATIC_YML_FILE}")

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(NONE)

# NORDIC SDK APP START
target_sources(app PRIVATE
 src/main.c
)
# NORDIC SDK APP END

# Add include directory for board specific CAF def files
zephyr_include_directories(
 configuration/${BOARD}
 )

target_sources_ifdef(CONFIG_CAF_SAMPLE_LED_STATE
 app PRIVATE src/modules/led_state.c)

fixed with adding \" \" when applying value to variable 
 cmake_minimum_required(VERSION 3.20.0)

set(PM_STATIC_YML_FILE \"${CMAKE_CURRENT_SOURCE_DIR}/pm_static.yml\")
message(STATUS >>>>>>> "PM_STATIC_YML_FILE: ${PM_STATIC_YML_FILE}")

#INFO this fixes the prj.conf issue with custom Private MCU BOOT Key
set(mcuboot_CONFIG_BOOT_SIGNATURE_KEY_FILE \"${CMAKE_CURRENT_SOURCE_DIR}/private.key\")

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})

project(none)

FILE(GLOB app_sources src/*.c)

target_sources(app PRIVATE
 ${app_sources}
 )
